    2. Download LG Root
    3. Use ADB Shell to copy the files to the temp directory on the phone
      adb.exe push busybox /data/local/t<span id="searchBubble" class="searchBubble"></span>mp/ &amp;&amp; adb.exe push lg_root.sh /data/local/tmp &amp;&amp; adb.exe push UPDATE-SuperSU-v2.46.zip /data/local/tmp
    4. Reboot into Download mode
    5. Use ports.bat to determine the DIAG port of the phone (Mine was COM 4)
